摘　　要：齿轮传动系统是机械传动中应用最广泛的传动机构,其工作性能对整个设备都有着至关重要的影响。为了避免齿轮系统在啮合过程中的振动,对其进行了动态特性仿真分析。以某型机床的直齿轮系统为例,首先通过采用SolidWorks2008软件对该齿轮系统进行参数化设计并建立其三维实体模型;然后将建立好的参数化模型导入到有限元分析软件ANSYS中,运用有限元分析软件ANSYS对其进行模态分析,并获得该齿轮系统的前6阶固有频率和振型。该模态仿真分析结果为齿轮系统的动态优化设计提供参考依据。Gear transmission system is used most extensively in mechanical transmission and its working performance has a crucial impact on the whole equipment.In order to avoid vibration of gear system in engagement process,dynamic performance is simulated and analyzed by using finite element method.It focuses on parameterization designing and building solid model of the wheel gear by using the software SolidWorks2008 based on the straight gear system of a certain machine tool firstly.Then,the parameterized model is leaded into the finite element analysis software ANSYS.The previous six natural frequency and mode of vibration of this gear system can get through model analysis which adopts the finite element analysis software ANSYS.The results of model analysis provide references to dynamic optimization design of the gear system.
